20# 2.0.51, we now have support for installing libraries to lib32/lib64 13# home rather than having multiple ebuilds implementing the same thing.
21# to accomidate the needs of multilib systems. It's no longer a good idea
22# to assume all libraries will end up in lib. Replace any (sane) instances
23# where lib is named directly with $(get_libdir) if possible.

59# in some cases when linking dynamic, the .a in /usr/lib is used
60# instead of the .so in /lib due to gcc/libtool tweaking ld's
61# library search path. This cause many builds to fail.

68# Note that you should in general use the unversioned name of

149# @FUNCTION: eshopts_push
150# @USAGE: [options to `set` or `shopt`]
151# @DESCRIPTION:
152# Often times code will want to enable a shell option to change code behavior.
153# Since changing shell options can easily break other pieces of code (which
154# assume the default state), eshopts_push is used to (1) push the current shell
155# options onto a stack and (2) pass the specified arguments to set.
156#
157# If the first argument is '-s' or '-u', we assume you want to call `shopt`
158# rather than `set` as there are some options only available via that.
159#
160# A common example is to disable shell globbing so that special meaning/care
161# may be used with variables/arguments to custom functions. That would be:
162# @CODE
163# eshopts_push -s noglob
164# for x in ${foo} ; do
165# if ...some check... ; then

142# This function is for bulk patching, or in theory for just one 265# @FUNCTION: epatch
143# or two patches. 266# @USAGE: [options] [patches] [dirs of patches]
267# @DESCRIPTION:
268# epatch is designed to greatly simplify the application of patches. It can
269# process patch files directly, or directories of patches. The patches may be
270# compressed (bzip/gzip/etc...) or plain text. You generally need not specify
271# the -p option as epatch will automatically attempt -p0 to -p5 until things
272# apply successfully.
144# 273#
145# It should work with .bz2, .gz, .zip and plain text patches. 274# If you do not specify any patches/dirs, then epatch will default to the
146# Currently all patches should be the same format. 275# directory specified by EPATCH_SOURCE.
147# 276#
148# You do not have to specify '-p' option to patch, as it will 277# Any options specified that start with a dash will be passed down to patch
149# try with -p0 to -p5 until it succeed, or fail at -p5. 278# for this specific invocation. As soon as an arg w/out a dash is found, then
279# arg processing stops.
150# 280#
151# Above EPATCH_* variables can be used to control various defaults, 281# When processing directories, epatch will apply all patches that match:
152# bug they should be left as is to ensure an ebuild can rely on 282# @CODE
153# them for. 283# if ${EPATCH_FORCE} != "yes"
154#
155# Patches are applied in current directory.
156#
157# Bulk Patches should preferibly have the form of:
158#
159# ??_${ARCH}_foo.${EPATCH_SUFFIX} 284# ??_${ARCH}_foo.${EPATCH_SUFFIX}
285# else
286# *.${EPATCH_SUFFIX}
287# @CODE
288# The leading ?? are typically numbers used to force consistent patch ordering.
289# The arch field is used to apply patches only for the host architecture with
290# the special value of "all" means apply for everyone. Note that using values
291# other than "all" is highly discouraged -- you should apply patches all the
292# time and let architecture details be detected at configure/compile time.
160# 293#
161# For example: 294# If EPATCH_SUFFIX is empty, then no period before it is implied when searching
295# for patches to apply.
162# 296#
163# 01_all_misc-fix.patch.bz2 297# Refer to the other EPATCH_xxx variables for more customization of behavior.
164# 02_sparc_another-fix.patch.bz2
165#
166# This ensures that there are a set order, and you can have ARCH
167# specific patches.
168#
169# If you however give an argument to epatch(), it will treat it as a
170# single patch that need to be applied if its a file. If on the other
171# hand its a directory, it will set EPATCH_SOURCE to this.

555# of these three directories to exist will be the one to use, ignoring
556# any more general directories which might exist as well. They must end
557# in ".patch" to be applied.
558#
559# User patches are intended for quick testing of patches without ebuild
560# modifications, as well as for permanent customizations a user might
561# desire. Obviously, there can be no official support for arbitrarily
562# patched ebuilds. So whenever a build log in a bug report mentions that
563# user patches were applied, the user should be asked to reproduce the
564# problem without these.
565#
566# Not all ebuilds do call this function, so placing patches in the
567# stated directory might or might not work, depending on the package and
568# the eclasses it inherits and uses. It is safe to call the function
569# repeatedly, so it is always possible to add a call at the ebuild
570# level. The first call is the time when the patches will be
571# applied.
572#
573# Ideally, this function should be called after gentoo-specific patches
574# have been applied, so that their code can be modified as well, but

920# basically look for the first lseek command (we do the strings/grep because
921# sometimes the function call is _llseek or something) and steal the 2nd
922# parameter. here is an example:
923# root@vapier 0 pdv_unpack # strings hldsupdatetool.bin | grep lseek
924# lseek
925# root@vapier 0 pdv_unpack # strace -elseek ./hldsupdatetool.bin

1175#
1176# A temporary hack until portage properly supports DEPENDing on USE
1177# flags being enabled in packages. This will check to see if the specified
1178# DEPEND atom was built with the specified list of USE flags. The

1181# The default is to abort (call die). The -a and -o flags control
1182# the requirements of the USE flags. They correspond to "and" and "or"
1183# logic. So the -a flag means all listed USE flags must be enabled
1184# while the -o flag means at least one of the listed IUSE flags must be
1185# enabled. The --hidden option is really for internal use only as it
1186# means the USE flag we're checking is hidden expanded, so it won't be found
1187# in IUSE like normal USE flags.
